WARP-DYEING MACHINE.

Specification of Letters Patent.

Patented Aug. 3, 1915.

Application filed June 19, 1913, Serial No. 774,689. Renewed January 23, 1915. Serial No. 4,076.

I '0 (ZZZ whom it may concern Be it known that I, JOHN G. KING, a citizen of the United States, residing at Burlington, in the county of Alamance and State of North. Carolina, have invented a new and useful lVarp-Dyeing Machine, of which the following is a specification.

The device forming the subject matter of this application is adapted to be employed in cotton mills for dyeing and coloring what are known as chain warps, each warp being a long strand, comprising a plurality of warp threads and including from four hundred to two thousand ends, the warp ordinarily having a diameter of from one-quarter of an inch to one inch, and being from twelve hundred to two thousand yards long.

The warps in operation, pass out of a suitable receptacle, across the top of a frame, and thence pass back and forth across rollers which are located in the dyevat. From the vat, the warps pass between an actuating roller and a compression roller, and thence pass by way of receiving rollers, into suitable receptacles, provided for holding the dyed warps. The actuating roller cooperates with the compression roller to draw the warps through the vat and over the rollers or spools which are located in the vat. All of the warps are actuated from a single source, to wit, the driving roller and the compression roller, and considerable difficulty has been experienced hitherto, by reason of the fact that each roller or spool in the vat, which receives more than one warp, is a unitary structure. The warps, as hereinbefore stated, are actuated from a common source, but when all of the warps travel over a single roller in the dyevat, some of the warps move with the roller in the dyevat and others of the warps are dragged on the roller, independently of the roller, because all of the warps and the single roller, are not traveling at the same speed.

One object of the present invention is to provide a machine of the type above described, with a plurality of individually rotatable spools located in the dyevat, each spool being adapted to receive one warp, whereby such spool may be actuated alone, by its individual warp, the consequence being that all warps move through the vat under equal tension, all of the warps being supported, in the vat, by their individual rollers or spools. As a consequence of the foregoing, the dyeing of the warps proceeds evenly and the warps are under a common tension.

It is within the scope of the invention to improve generally and to enhance the utility of, devices of that type to which the present invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing :Figure 1 shows in side elevation, one form of machine to which the present invention has been applied; Fig. 2 is a horizontal transverse section of the structure shown in Fig. 1 on the line 2-2 of Fig. 1.

In carrying out the invention there is provided a supporting structure which is de noted generally by the numeral 1. The supporting structure 1 comprises a dyevat 2 and a frame 3. At this point it may be stated that the support, comprising the vat and the frame, may be fashioned variously, without departing from the spirit of the invention, the structure, in the present instance, having been shown in a simple form, in order to avoid complexity in description and illustration, and to avoid a confusing of what is old with what is new.

The frame 3 in the present instance is shown as comprising posts a, the posts 4: at each side of the frame being connected by longitudinal bars 5, 6 and 7, the bars 5, if desired, resting on top of the vat 2. Braces 8 project from the' rear posts 4 and support inclined arms 9, which are connected with the upper bars 7. The arms 9 are connected by slats 11 and the bars 7 are connected by slats 10. Upstanding from the slats 10 and 11 are pins 12 between which the warps pass.

In the present embodiment of the invention, a cross beam 14 is supported by the bars 5, the cross beam upholding slotted standards 15 receiving bearings 16 in which is journaled for rotation a shaft 17. Located above the shaft 17 is another shaft 18, held in place for vertical movement by a bearing 19. A driving roller 20 is secured to the shaft 17 and a compression roller 21 is carried by the shaft 18. To one end of the shaft 17 may be secured a wheel 23 about which is trained a belt 24, constituting means for actuating the shaft 17 and the driving roller 20, although, obviously, the shaft 17 may be actuated in any desired Mounted on the braces 8 are bearings 25 in which is journaled a receiving roller 26. The receiving roller 26 is operatively connected to the shaft 17 by means of a sprocket chain 27. Bearings 28 are mounted upon the arms 8 and in the bearings 28 is journaled another receiving roller 29, the rollers 26 and 29 being operatively connected by means of sprocket chain 30.

Mounted upon the supporting structure 1 V and in the present instance connected with the bars 5 and 6 are vertical guides 31. Mounted to slide in the gu des 31 and'adapt- .ed to dip into the vat 2 are hangers In each pair of oppositely disposed hangers 32, upper and lower shafts are supported. Journaled for rotation upon each of the shafts 33 are individually rotatable spools 3 1. There may be any number of shafts 3S, and any number of spools 3% may be mounted upon each shaft. Ordinarily, but not necessarily, the machine is constructed to handle about a dozen warps.

The warps 36 are contained in bags 85, and from the bags 35, the warps 36 are carried upwardly over the slats l0 and ll between the pins 12, the warps being thence lead downwardly into the at 2, vand being trained to and fro over the spools 34:. From the spools 3 1-, the warps pass between-the drive roller 20 and the compression roller 21, some of the warps passing thence over the receiving roller 26 and others of the wraps 3(3'passing over the receiving roller 29. From the receiving rollers the warps are led downwardly into receptacles 37.

In practical operation the shaft 17 is driven through the medium of the wheel 23 or its equivalent, the driving roller 20 being Copies of this patent may be obtained for five cents each, by addressing the thus actuated, and the driving roller 20 cooperating with thecompression roller 21, to advance the warps 36 through the vat 2 and around the spools 34. Owing to the fact that the several spools 34 are individually rotatable upon their respective shafts 33, each spool 34 is driven by the friction of one warp only. As a consequence, each warp moves freely through the vat 2 and there is no forcible dragging of any one warp over a roller or spool, the speed of rotation of which is held back by other warps, it being noted that each warp while the same is in the vat 2, is controlled by a series of spools 31 which is peculiar to that arp only.

Havin thus described the invention,what is claimed is "in a warp dyeing machine, a supporting structure including a dye vat;'a shaft supported in the dye vat; a plurality of warp receiving spools individually rotatable upon the shaft; a single means for drawing all of the warps at once through the vat and around the respective spools; the spools being terminally spaced from each other to avoid friction between thespoo-ls and to permit the several spools to rotate inde .pendently'under the action of their respective warps, the spools tapering fromtheir:

ends toward their central portions, whereby the spools will be held terminally spacedby the action of the respective warps; and a warp guiding and spacing means including relatively fixed elements coiiperating with the several warps before the same pass onto the spools, to prevent a bunching of the warps and a crowding of the spools into terminal contact. V Y In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
